MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files, identified as a link farm. While the document body is heavily corrupted, the presence of numerous links suggests an attempt to manipulate search engine results or direct users to potentially malicious content. No scripts were extracted, but the overall structure and heuristic firings indicate a malicious intent to distribute content via a link farm.
